Here’s a recent example.
If you are STUCK in an intractable problem, RE-ESTABLISH YOUR BASIC ASSUMED KNOWLEDGE. ~~GO BACK~~
What told you this was a problem? What does EVERY relevant log say in that timeframe and in general? Do the underlying protocol negotiations even work?

Point is - trust nothing. Re-verify what you're told. Even if they're smart. *Especially* if they're smart. Smart people like to assert what they believe is true as being verified truth, and often get offended you'd doubt them. Step on toes and confirm base assumptions.
